Detailed Description FFA MATRIX DSP
FFA MATRIX DSP is a line-level loudspeaker management controller with four analogue inputs and eight analogue outputs. Input and output pairs can be switched in software between analogue and AES/EBU operation. Its routing choices include a mix matrix, free routing and predefined configurations, allowing the processing structure to follow the loudspeaker system.
Signal processing and routing
Each input provides a soft-knee compressor, high-pass filtering, six parametric EQ bands, a 28-band graphic equaliser and three bands of dynamic EQ. Gain, polarity and delay up to 1.3 seconds are available for input alignment and processing. These functions allow source signals to be prepared before they enter the output-routing matrix.
Output processing includes eight parametric EQ bands, two dynamic-EQ bands, crossover filtering up to 48 dB/octave and delay up to 1.3 seconds. PXL limiting is provided to control loudspeaker power with the manufacturer’s Predictive eXcursion Limiter algorithm. Flexible channel linking supports repeated crossover structures and custom system configurations.
Control and documentation
FATWARE provides network control for PC, Mac and iPad, including multi-device setup, offline design and preset-library management. The published interfaces are 100 Mbit/s Ethernet and USB Type B, with up to 30 presets for offline recall. FFA lists this model as no longer in production; the archived datasheet remains available for identification and support of installed systems.
